Fruit Pastels are a British candy product designed to be chewed—they're sticky, flavorful, and have a chewy texture that makes teeth-less consumption impossible for ordinary humans. Chuck Norris supposedly can consume one without chewing, implying that his mouth has transcended the normal dietary requirements of texture and structure breakdown. He can swallow difficult objects whole, his throat somehow bypassing normal anatomy.

A candy company executive from London supposedly joked in 1998 that "if Chuck Norris can do it, we might have a marketing angle here: 'Impossible to resist. Impossible to chew. Just like Chuck Norris."

Food blogs adopted this: "Gum companies have a mascot. Fruit Pastels have Chuck Norris."
